I don't usually put ketchup on my fries, but occasionally, especially with some kinds of fries, I do. When that happens I dip my fries into a puddle of ketchup, as on the left.

Doing it like on the right results in squishy spots on some fries where ketchup has been sitting while you eat other fries, and one has to be careful to grasp the french fries in such a away as to avoid the ketchup squirts--just digging in and grasping the squishy ketchup parts directly is gross.

ETA: Oops, Sorry MK. I didn't mean to imply that you were gross. Your fries kink is okay even if it's not my kink

To be fair, with my kink, I eat the loaded fries with a fork, since it's more of a dish and less of a finger food at that point So no worries of grasping and squishiness.

(Not to imply that I am not gross, however.. or at the very least quite strange...)
